Here’s a password strength tester, and probably one of the most effective I have seen. Just enter your password in the text box and click on the search button. If you get no results, chances are your password is pretty good.

I think many of you will be very be surprised how common your “secret” password really is:

No, this isn’t a joke and no this isn’t a way to collect your passwords. The point is that Google is actually an excellent way to see how strong your passwords are. Open a new Google search window directly if you don’t want to use this form.

Just remember that searches aren’t encrypted with SSL and Google even keeps a search history on you so you probably should be careful about what you send. I usually try passwords I have used in the past or passwords using a similar pattern rather than entering an actual password.
